The General Radio 1432-W Decade Resistor was in Catalog S (1965) only.
The Type 1432-W is a decade resistance box comprised of six Type 510 decade resistance units in series, for a total resistance of 11,111.1 Ω in steps of 0.01 Ω.
The 510 decade units use an 11-position switch, with the first position shorting the decade, and the following positions increasing the resistance by one step. The switch has a make-before-break configuration, i.e. regardless of the position there is always continuity between the terminals. The terminals are Type 938 equipped with a shorting link to the case. The decades are housed in an aluminum case shielded and insulated from its resistance terminals.
